HENRY KELLY, OF THE BOROUGH or MANATUNK, PHILADELPHIA COUNTY, PENN-sTLvANIA.

JACQUAED. f l' i Specification of Letters Patent 1\To..5j,9.:`i?,y datedNovember 28, 1848.

Be it known that I, HENRY KELLY, of the borough of Manayunk, in thecounty of Philadelphia and State of Pennsylvania, have invented new anduse Improvements in J acquard-Machines, so as to .weave figured or plaincloths or other woven fabrics thereby withoutfaJ square axis (usuallytermed cylinder cr pat-tern cards and so as to raise and sink or depressalternately the sheds of the warp equally, and thus to adapt the saidmachine better for power-looms than it heretofore has been; and I dohereby declare that the following is a full and exact description of thesaid improvements, reference being made to the annexed drawings andindex thereof, as part of this specification.

In lieu of the square or four faced cylinder, `with its four-coggedwheel and pattern ycards thereon, (as heretofore used in the saidmachine) I place a round cylinder (B Figures l and 2)'-into theperiphery or surface whereof I bore, in straight lines lengthwise of thecylinder, any requisite number of small holes into which I fasten pins(by screws cut into them or otherwise and common screw nails forfastening into wood will answer as these pins), so that in weaving, eachpin in the row lwill push one of the needles of the machine in adirection from the cylinder. These needles I arrange so that their endsform one straight row or file parallel with the cylinder; and in each?needle are two holes or eyes through each of which passes one of theupright hooks. To the lower ends of the twohooks passing through thesame needle a shaft or heald is attached by its ends, and the needle,being pushed by one of said pins, causes the shaft to be moved evenly upor down by this pair of-hooks, and so on with every needle that may berequired to form the desired figure in the web. The pins are intended,the same as the holes in the pattern cards,to form the figure sought tobe woven; and may be carried in the cylinder so as-to produce the sameeffect as the pattern cards heretofore cut through the cards; but notliable to be displaced, by rapid motion, as cards are. On the end of thecylinder I fix a cogged wheel (c c Figs. l and 2) in the teeth or cogsof which the catch (cl Fig. l) works; and when the sliding or liftingframe (A Fig. 1 sometimes called the griff frame) lis moved upward, thecylinder is moved around by Val@ Said @ach assistance ef one moth orcog; the number of teeth or cogs in the wheel, 1s equal to the number ofrows of pins vin the cylinder, and is equal in effect to the same numberof treadles in a common loom; l

because every tooth of the wheel that is thus moved causes so manyshafts or healds, as

the figure may require, to be acted on in order to draw the lower shedof the warpdown as far as the upper shed is raised; and thereby preservethe tension of the warp as equal as possible. I place a pair of racks (gg Figs. 4 and 5) in each end of the slid- Ing frameV or griff, withtheir teeth toward each other; one of each pair of those racks isfastened to and moves up and down with the sliding frame the other ofeachpair of racks slides up and down in a groove; and between each pairof these racks I place a pinion (la Fig. 5), turning on a fixed centralpivot, and its teeth or cogs working into those of both rackssimultaneously. This pinions center being immovable,- it is turnedpartly around by the fixed rack as it rises and falls with the slidingframe or griff; and the pinion, by this movement, causes the oppositerack to move in its groove the same distance with the fixed rack, but inthe opposite direction. The hooks that the woven figure requires to beraised are lifted by the lifting bars of the sliding frame or griff; andthe rest of the hooks, being suspended on rods as (J Fig. 3) passingthrough the open slit in the lower end of each lifting hook, are at thesame time depressed a distance equal to that which the former hooks arelifted. The ends of these rods are fasmuch cheaper than if made by themachinery heretofore used, whether operated bymanual labor or othermotive power.

What I claim as my invention, and desire to secure by Letters Patent, isnot the said cylinder or polygon, cogged wheel, racks, pinion, or any orall of them; but

WhatI so claim and wish so to secure is- The combination, application`and use of the said round cylinder with pins or screws in its surfaceand; cogged wheel Onets end,V

machine, as described in the fication; A

In testimony whereof I hereunto set my foregoing speci- 10 `hand and aXmy seal, this twenty-eighth day of September A. D. 1848.
